NAIL-HEAD, 80C.

SPECIFICATION forming part of Letters Patent No. 440,364, dated November11, 1890.

Application filed December 6, 1889. $erialNo. 332,808. (No model.)

To all whom it may concern:

Be it known that we, JOHN B. PERRAUD and WILLIAM BEoHToLD, bothresidents of the city, county, and State of New York, have inventedcertain new and useful Improvements in Heads for Nails, Buttons, &c., ofwhich the following is a specification.

The object of our invention is to connect a head for nails, buttons,&c., with the stud or shank by which the head is secured to a nail,board, fabric, or the like.

The invention consists in the novel details of improvement and thecombinations of parts that will be more fully hereinafter set forth, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming parthereof, wherein- Figure 1 is a side view of a nail and its headconnected together according to our invention. Fig.2 is a centrallongitudinal section enlarged on the plane of the line y y, Fig. 3.

Fig. 3 is a cross-section 011 the line a: :r, Fig.

2, showing the inner side of the nail or button-head having a perforatedplate or washer attached. Fig. 4 is a detail face view of said plate orwasher, showing part of the split stud passing through the plate; andFigs. 5, 6, 7, 8, 9, and 10 are detail views, hereinafter more fullyspecified.

Referring now to the accompanying drawings, the letter A indicates ahead for nails, buttons, and like articles, and B indicates a nail,screw, or the like, to which the head A is to be attached.

D is a stud, screw, or shank to be secured to the head A.

E is a plate or washer placed on the inner side of the head A andsecured thereto. The plate or washer E is provided with a series ofholes a, and the head A is cast upon said plate or washer, so that thematerial of the head will pass through said holes, and thereby hold theplate to the head. Said plate or washer also has an aperture 1), throughwhich the stud, shank, or screw D may pass,as shown. One end of thestud, shank, or screwD passes into the head A, and to secure it in placethe head is cast around the stud. In order to more securely hold thestud, shank, or screw to the head A, one end of said stud is widened orforked, and the prongs d d bent outwardly, as shown,'so that thematerial of the head A will envelop said prongs d, whereby the stud,shank, or screw D is securely held to the head A. ith the abovearrangement the head A may be made of cast glass, and the studor screwsecured in it without danger of the parts becoming separated. By makingthe holes a in the plate or washer E, and casting part of the materialof the head A through said holes, the plate or washer will not turn onthe head A when a twisting strain is put upon the washer. The outer endof the stud or shank D (shown in Figs. 2 and 3) is split or forked,forming prongs f, which have an outward spring tendency, and when passedinto an aperture or socket c in the nail B, or else where, will, byfriction, hold the head A in place. The outer part of the socket c isWidened or made cone-shaped, so that when the nail is driven the metalat the end of the nail will not be swaged over to close the socket. Bythe above arrangement the nail may be driven in a wall or other place 9and the head A afterward applied to the nail, so that the head will notbe broken when the nail is driven in the wall. The outer end of theshank D may be rounded, as in Fig. 2, or pointed or tapered to assist itin entering the socket e.

Instead of the stud or shank D having the forked end f and the nailhaving the aperture or socket e the stud or the head A may have thesocket e, and the nail have the forked end f to enter said socket, asclearly shown in Fig. 5. WVith the above arrangement the same effect isproduced as with the arrangement shown in Fig. 2.

In Fig. 10 the forked stud D,which is to be secured to the head A, as inFig. 2,is more pointed at its ends than in Fig. 2, so that it can bemore readily passed into the socket e or through fabric or the like.

In Fig. 8 the outer end of one prongfof the stud or shank D is providedwith an aperture h, through which the opposite prong f may be passed,whereby the stud or shank may be made to envelop a bar or other object.

In Fig. 6 the part D is shown in the form of a screw, whereby the head Amay be secured in place without the aid of the nail B.

In Fig. 7 the part of the stud, shank, or screw D that enters the head Ais flattened out to widen it, whereby it will be prevented from becomingdetached from the head A. hen

the part D is in the form of a screw, we prefer to make the part of theshank that remains in the plate or Washer E square or flat, and to makethe aperture 1) on said plate correspond. By this means, when the head Ais turned, the plate or Washer E Will assist in turning the screw.

In Fig. 9 the stud or screw passes entirely through the head A and theplate or Washer E, and the stud is threaded through only a part of itslength, so that it will hold the head A tight against a board or thelike.

The shank D may be smooth, corrugated, threaded, apertured, or otherwisearranged, as desired;

Having now described our invention, what we claim isv 1. The shank D,having one end widened or enlarged and its opposite end forked, combinedwith the head A, that receives the widened end of the shank, and withthe nail B, having a socket e, that receives the forked end of the shankD, substantially as described.

2. The shank D, having a square or flattened portion and a widened end,combined with the head A, into which said widened portion projects, andwith a plate or washer E, secured to said head, and having an aperture6, that corresponds in shape with the squared or flattened portion ofthe shank, said squared portion of the shank fitting within the apertureb, so that the shank and-washer will turn in unison, or one turn theother when the head A turns, substantially as described.

3. The shank D, having one end widened or enlarged and the opposite endsplit or forked, combined with the head A, that is cast around saidwidened end, substantially as described.
